Application led October 14, 1911. Serial No. 654,742.

To all whom it may concern.'

lle it known that we, Josnrn Lnoins and EDGAR S. Lucius, citizens of the United States, residing at Bourbonnais, in the county et Kankakee and State of Illinois, have invented new and useful Improvements in Fortable Conveyors, of which the following is a specification.

The invention relates to -conveyers, and more particularly to the class of portable adjustable and knock-down conveyors.

The primary object et the invention is the provision of a portable conveyer which can be readily knocked down and folded into compact form for the easy and convenient transportation thereof.

Another object of the invention is the provision of a eonveyer of this character in which the sections thereof are connected in a novel manner so as to permit the extend ing or contracting of the `conveyer without the possibility ot` the separation of the sections.

A further object ot' the invention is the provision ot a conveyer which can be quickly swung from one side to the other so that the cribs may be operated upon.

A still further object 0f the invention is the provision of a conveyer in which the horizontal sections may be vertically adjusted at either or both ends as may be required.

A still further object of the invention is the provision of a conveyor which is simple in construction, light in weight, yet possessl ing the requisite strength, and that will he` thoroughly reliable and etticient in opera-. tion, and inexpensive in 1nanutaclure.-

' With these and other objects in View, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illus' trated in the accompanying drawings, and; pointed out. in the claims hereunto.

Fig. l5 is a perspective view of the rack frame. Fig. 1G is a perspective view `of one of the brackets 132 detached.

Similar reference characters indicate cor.-- responding parts throughout the several views of the drain ings.

Referring to the drawings/by numerals, l() designates the traine et a corn shelling machine of any tndinary ivelliknown construction, thefranie being,supported upon wheels ll, as usual, whereby it may be to another. Upon the frame is mounted a drinn or Cylinder l2, in which arranged corn she ling mechanism ot any approved type. the drum or cylinder l2 being :termed with an inletl chute or mouth extension 13, into which is celivcred the corn to be shelled and with which communicates a detachable and rotary delivery hopper, presently described.

The conveyer coinurises an extensible horizontal crib, section, and an elevator crib section, the extensible section serving as a wagon box for the transportation ofthe eoni vcyer, and including trames il., 15,16 and. llrespectively, each col'ninising vertical side `walls "1S, closed bottoni 19, and open topt), the said side walls 18 being connected atithe'onen ton Q0 bv means of cross braces 21, so as to prevent the lateral spreading vor contraction of the said side Walls of the frame. To the cross lbraces 21 of the frames 14 and 17 respectively, are fixed sta- -The frame 14 isof greater length than 4 the other framesof he horizontal crib section, and at the inne -ends of the side walls 18 thereof, on the outer faces of the same, are fixed .metallic plates 27, which are bolted or otherwise secured thereto, the said plates being formed with outwardly extending studs 28, on which are journaled hook-like latches 29 which are adapted to lock with hook-like keepers 30 formed on the inner ends -of the side walls 18 of the frame 17 for detachably connecting the said frames 14 and 17 together, when the frames 15 and v 16 have been telescoped within the frame 14.

Formed on the plates 27 are bearing lugs 31' which are adapted to engage with and overlap bearing lugs 32 formed on the side walls of the frame 17, thus serving to prevent the vertical displacement of the frames 14 and, 17 when connected together. The outer ends of the frames 14 and 17 are closed by means'of vertical end walls On the outer end of the frame 17 and rising from the side walls 18 thereof are. substantially goose-neck shaped extensions 34 formed with bearing terminals 35, with which aline further bearings 36 formed on and projecting outwardly from the side walls 18 of the said frame 17, and in these bearings are fixed vertical guide rods 37 embraced by the sleeve terminals 38 of the limbs 39 of a Acaster supporting bracket, the limbs 39 converging toward each other and being formed with a centrally located sleeve 40, in which is journaled vthe stem 41 of a turning fork 42 supporting a rear guide wheel or caster 43. rlhe stem 41 has threaded thereon a lock nut 44 of the usual form, the sleeve terminals 38 of the limbs 39 of the-bracket being vslidably engaged with the rods 37, so that the wheel 43 may be vertically adjusted, in a manner presently. described.

Journaled transversely in the limbs 39 of the bracket is a turning' shaft 45 provided with pinions 46, meshing with rack gears 47 loose upon a shaft 48 journaled in the sleeve terminals 38, the gears 47 meshing with stationary racks 49 fixed to the front wall of the frame 17. Thus it will be seen that upon turning the shaft 45, the bracket supporting the wheel 43 .may be vertically adjusted for the raising and lowering of the front end of the horizontal crib section.

Fixed to the inner faces of the side walls 18 of the frames 14 and 15, and also the bottoms 19 and cross braces 21 thereof, are the supporting bases 50 of friction rollers 51 which permit the free telescoping of the frames 15 and 1.6, without binding thereof, When the same are moved inwardly into the frame 14, as will be apparent. Fixed to the inner faces of the side walls 18 of the frames 14, 15 and 16 are forwardly inclined guide tracks 52, the outer ends of vwhich are formed with loops 53, in which engage friction rollers 54 fixed exteriorly of the side walls 18 of the frames 15 and 16, said rollers 51 being adapted to travel upon the guidetracks4 52 on the telescoping of the said frames in the frame 14, but when the rollers 54 are engaged in the loops 53, the frames in upstanding position. Mounted at the upper edges of the side walls 18 ofthe frames 14, 15 and 16 are pivoted trip latches 55, which are adapted to drop into position when the Arollers 54 are engagedin the loops 53, and thereby intersect the path of movement -of the rollers 54 to hold the. frames locked in upstanding position. However, it will .be seen that byraising the triplatches 55, the rollers -will be freed for disengagement from the loops 53 of the guide tracks 52 for permitting Vthe telescoping of the frames 15 and 16 inthe frame 14 of the conveyer section.

Near the close end of the frame 17 and fixed to the inner faces of the side walls 18A thereof are notched racks 56, in which are engaged the ends of a cross connecting rod 57 of a rack frame 58, the same'being provided with elongated slots 59, through which is passed a rotatable and supporting shaft 60 having loosely mounted thereon rack pinions 61 adapted to mesh with the ,will be prevented from pulling apart when j rack `teeth 62 formed on the frame 58, the

said shafts being also provided with loose locking pinions 63 which engage the rack teeth 62 for holding the shaft 60 in adjusted position in the rack frame 58, for the tightening andloosening of an endlessconveyer belt or apron 64 trained overV a guide roller 65 supported by said shaft 60 between the rack frames, the belt being also trained over ay guide roller 66 fixed to a shaft 67 journaled in the sidewalls 18 of the frame 14, at the forward end thereof, and upon this belt or apron is adapted to be poured the ears of corn to be conveyed thereby to the elevating mechanism of the conveyer, presently described.

Fixed to the outer or forward `end of the frame 14 are vertical posts 68, to whicha'rc pivotally connected swinging arms 69 havingv pivoted thereto adjusting brackets 70 Lome-54 provided with elongated Vslots 71, in whichj are engaged locking bolts 72, and in this manner the arms maybe held in adjusted position at the required angle. Mounted on the outer ends 'of the swinging arms 69 are forked coupling members 73 for the detachg able connection ofthe horizontal crib section with the elevator ycrib section, presently described. L The elevator crib section comprises an in- 'clined frame 74 prcvided withthe usual side boards 75, the frame and side boards being,

extended at the lower ends thereof to formi a receiving extension 76, disposed at an acute angle 'to the major portion of thel frame, the said extension 76 being provided` With a hopper-shaped mouth 77, into which is 'fed the corn ears from the conveyor belt "or apron 64 `in `the horizontal crib section.

Journaled transversely in the side boards 75, both at the upper end of the frame 74 and the extension end 76 of the elevator section, are shaft-s '7S and 79, respectively, having fixed thereto the usual guide rollers '80, over which is trained an endless elevator apron or belt 81,the upper end of the frame communicating directly with the open end of a hopper body 82, rotatably7 and 4det-achably engaged in the mouth end of the chute 13 of the corn shelling machine, the said hopper being formed with an annular outturned fiange 83 adapted 'to rest upon the vrim S4 of the open mouth of the chute 13, the said flange and rim being provided with suitable registering openings to receive a securing pin 85 detachably held therein, for the fastening of the hopper body 82 upon the chute 13 of the vcorn shelling machine. This hopper body 82 has fixed thereto a cast-ing 86 provided with spaced bearings S7 and 8S, respectively. In the bearings 8-8 is journaled a shaft 89, to one end of which is xed a sprocket 90, over which is trained an endless sprocket chain 91, the same being also ytrained over a sprocket 92. fixed to one end of the shaft 78, the latter having fixedA thereto a further sprocket 03, over which is trained a sprocket chain 04, the same being also trained over a sprocket .95 journaled upon a stud shaft 9G, projecting outwardly from one side of the -frame 74. This sprocket 95 is in the nature of a double sprocket, so as to carry a further sprocket chain 97 to be trained over the saine, which chain is also trained over a sprocket 9S fixed to a shaft 99, the latter supported in a forked bearing 1.00 mounted on the free ends of horizontally disposed rearwardly extending beams 101 fixed to the side boards 75 of the elevator frame 711, the said beams 101 being braced by vertical standards 102 fixed to the extension end 7 6 of the said elevator frame.

On the shaft 99- is a beveled gear 103 meshing with a beveled gear 101 on a shaft 105 vertically journaled in a fork 10G carry'ing a further beveled gear 107 meshing with a beveled gear 10S fixed to a shaft 109 journalcd in the .fork 10G, the shaft 109 being provided with a sprocket 110, over which is trained an endless chain 111 Which is also 'trained over a sprocket 111a fixed to the shaft 67. rThus in this manner, the endless apron G11 will be driven simultaneously with the apron `81. in the horizontal and inclined cribs, respectively. The shaft 109 is adapted to be inserted in the forked couplings 73 for connecting the horizontal crib section to the elevator crib section, the forked couplings being provided with detachabie locking pins 111b which sustain the couplings connected with the shaft 105, so as to prevent the separation of the seetions when connect-ed.

Mounted yon the extensions 34 rising from the frame 14 are forwardly extending supports 112, .in which is journaled a winding and nnwinding roller 113, on which is adapted to be wound the conveyer belt or apron Gel, when the frames 15 and 1G are telescoped within the `frame 14 of the horizontal crib section, the apron or belt (14 being unwound from the said roller 113 when the frames of vthe horizontal crib section are extended.

' @n the detachment of the horizontal crib section from the elevator crib section, there is adapted to be engaged with or attached to Athe front end of the said horizontal crib section a draft rigging, comprising a front axle 114, on which are journaled front supporting wheels 115, the axle being engaged by depending bearings 11G of a cross supvporting beam 117 formed with upturned ends 118, the frame '14, atA its front end, being adapted to rest upon the beam 117, and the upturned ends 118 are perforated to receive fastening pins 110, which engage in perfor-ations formed in keeper plates 120 'fixed to the side Walls 18 of the frame 111, at its front end. Fixed to the depending bearings 116 of the cross beam 117 are the limbs 121 of an inverted U-shaped bail or y-oke 122, which is adapted to engage in the forked couplings 73 and is locked therein by means of the pins 111b, .as will be clearly seen.

Connected to the bearings 116 of the croSs beam 117 is a forwardly extending draft pole 123, which is designed to be supported in substantially horizontal position, when' the holding rod 124. is del'a'c-hably connected to the said pole and loosely connected to the bail or yoke 122. Disposed at opposite sides of the elevator frame 74- arc posts 125, near the lower ends of which are fixed forwardly extending bearings 120, in which are journaled the stems orforks 127, in which are journalcd casier uheeis 128, the posts 125 being secured at their upper ends by means of a cross bar 129, while fixed to the lower in the horizontal beams 101 are eye bolts 133,

to which 'are ixed cables 134, the same adapted to be wound on and unwound froma windlass 135 fixed to a supporting shaft 13G journaled in bearings 137 mounted upon the posts 125, near the upper ends thereof. On one end of the shaft 136 is fixed a pulley wheel 138, over which is trained a band 139, the same being also trained over a pulley wheel 140 journaled upon one of the posts 125, the said pulley 140 being provided with' a turning crank 141 to be engaged by the operator for the turning of the pulley wheel 140, so that the cables 13 4 may be wound on or unwound from the windlass, for the raising and lowering of the lower end of the elevator frame 74, as will be obvious. The endless belts or aprons are held taut by ordinary well-known belt tighteners, andtherefore a detail .description of the same has been omitted. A

In the elevator section is arranged a roller 142, the same being disposed at the extension end thereof for uiding the lower stretch of the conveyer lt 81. Theroller 142 is mounted upon a shaft 143 lprovided with sliding bearings, said bearings being adjustable by means of follower screws 144 engaged in plates 145 fixed to the sides of the elevator section, it being understoodof course that the sides are slotted to accommodate the sliding bearings supporting' the said roller 142, so that the latter may be adjusted for tensioning the conveyer belt or apron 8l as desired. Engaged with'the upper stretch of the conveyer belt or apron 81 are guide members 146 which cause the belt or apron 81 to present a curvature at the proper point between the extension 76 and the major portion of the frame 74 of the elevator section.

What is claimed is:

1. In a conveyer, a horizontal crib section inclding a plurality of extensible sections, means locking the sections in extended relation to each other, means for vertically adjusting one end of said :horizontal crib section, an endless conveyer apron mounted for travel in saidv crib section, means for tightening the said apron, means on one of the sections ot the crib section for receiving the apron on retracting the said sections, and means for locking` the sections in retracted relation to each other.
